The main issue with enhanced lsl-to-client communication, like in
RestrainedLife that was mentioned as an example, is..
The change of behavior runs deep. RestrainedLife is not about the UI,
but direct client behavior for all sorts of things.
All effects and behavior that one'd want to be executed in the client
via messages coming from in-world would need to be implemented, and/or
at least selecteable. You'd have to have a either predefined messages
and commands with hardcoded effects, or some kind of template system
with which to program the viewer.
Added to that, the viewer'd need to allow for all kinds of implemented
functionality to be executed, given that the change'd not be for a
specifc system, but for people to build their own systems on (Again,
RestrainedLife was an example). The viewer architecture isn't that
easy. Implementing such a templating would be a huge undertaking, and
I see a huge potential for abuse as well if there is some kind of
IMO the best solution for such quite deep changes of behavior is to
simply make a modified client for a specifc system, like
RestrainedLife is today. It's by far the more secure approach, if you
want such enhanced client functionality triggered by in-world objects.
When it comes to UI changes only, I also think the other way around
would be much nicer...create an UI that is scriptable via a language
World Of Warcraft is an -excellent- example what people can do with a
programmable LUA UI.
